Creating session trough SFTP with SSH key is no working - cannot define username

[theLoFix]

Issue Description

I'm trying to open session with generated SSH key, but when open session module is trying to connect as anonymous user. How can I defined name of the user I want to be logged to? addinf Credential option will pop out password prompt...

Example

$sessionOptions = New-WinSCPSessionOption -HostName $Hostname -Protocol sftp -SshHostKeyFingerprint $SshHostKeyFingerprint -SshPrivateKeyPath $SshPrivateKeyPath -SecurePrivateKeyPassphrase $SecurePrivateKeyPassphrase

Expected Output

Connection should be established via SSH key on defined user.

Actual Output

New-WinSCPSession : Exception calling "Open" with "1" argument(s): "Connection has been unexpectedly closed. Server sent command exit status 0.
Authentication log (see session log for details):
Using username "anonymous".
Server refused our key.
Authentication failed."

I don't have anyway to test this, but your could try using the -Credential parameter. and passing it a [PSCredential] object. And you could try using a blank one as well -Credential ( [PSCredential]::new()).

Hello @dotps1.
I make a quick test of passing Object of Type, with only a username:
TypeName: System.Management.Automation.PSCredential

And this works!
I only used different action to create one:
$cred = Get-Credential
Code you suggested is form .Net I believe and it does not work on Power Shell, probably some Library is missing.
Never the less passing PSCredential object with username only, and without password provided on credential prompt works like a charm.
Thx for help.

I wanted to suggest a few more ideas.
my mistake, to create an empty PSCredential object, this is the way to do so:

[PSCredential]::Empty

You can also try to it like this to specify just a username:

[PSCredential]::new( "userName", [SecureString]::new() )

but you can use either of those in the -Credential parameter to avoid the credential prompt.
